If not already possible, random 'shuffling' of survey questions would be a nice feature, e.g. when these questions are about something referring to the experiment, not just basic demographics.
This should be an attribute which is specific for an individual 'pretest' or 'posttest' element, in situations where you only want to randomise the order of the questions immediately pre- or post- a page, not the post-test survey, for instance.

Taking it really far, you could 'group' a couple of questions and make sure these are always asked in that order, but then randomise the order of such 'blocks'. But I think that's over the top, unless there's a nice/elegant/standard way of doing this.

As a side note, I have made a 'survey-only' XML today and it worked beautifully. No reason why it shouldn't, but I was happy I could separate the survey from the rest if necessary.
